extension Data: XDRCodable

Extension providing base32 encoding and decoding for Data.

Supports both standard base32 (RFC 4648) and base32hex variants. Used extensively in Stellar’s StrKey encoding for account addresses and keys.

  • Encodes data to a base32 string.

    Uses the standard base32 alphabet (A-Z, 2-7).

    Example:

    let data = Data([72, 101, 108, 108, 111])
let encoded = data.base32EncodedString // "JBSWY3DP"

    Declaration

    Swift

    public var base32EncodedString: String { get }
    Show on GitHub

  • Encodes data to base32 format as Data.

    Returns the base32-encoded string as UTF-8 data.

    Example:

    let data = Data([72, 101, 108, 108, 111])
let encodedData = data.base32EncodedData

    Declaration

    Swift

    public var base32EncodedData: Data { get }
    Show on GitHub

  • Decodes base32-encoded data.

    Assumes the data contains a UTF-8 encoded base32 string.

    Example:

    let encoded = "JBSWY3DP".data(using: .utf8)!
if let decoded = encoded.base32DecodedData {
    // Use decoded data
}

    Declaration

    Swift

    public var base32DecodedData: Data? { get }

    Return Value

    Decoded data, or nil if decoding fails

  • Encodes data to a base32hex string.

    Uses the extended hex alphabet (0-9, A-V).

    Example:

    let data = Data([72, 101, 108, 108, 111])
let encoded = data.base32HexEncodedString

    Declaration

    Swift

  • Encodes data to base32hex format as Data.

    Returns the base32hex-encoded string as UTF-8 data.

    Declaration

    Show on GitHub

  • Decodes base32hex-encoded data.

    Assumes the data contains a UTF-8 encoded base32hex string.

    Declaration

    Swift

    public var base32HexDecodedData: Data? { get }

    Return Value

    Decoded data, or nil if decoding fails
